On Wednesday (Nov. 1), B.o.B. posted a video on Instagram and asked, "They say slavery lasted 400 yrs... America is only 250 yrs old... You ever seen a slave ship?" In the video, an unidentified man claims Europeans changed up chronology to confuse us.

"They can find a billion year old dinosaur bone but can't find any slave ships. #AseerTheDukeofTiers #apparently#SlaveryIsNotInMyDNA #WeBeenHere," B.o.B continued in his caption.

While the rapper may have never seen a slave ship, in 2015 the Smithsonian received artifacts from a sunken 18th-century slave ship. The artifacts come from the wreck of the São José-Paquete de Africa, a Portuguese ship en route to Brazil while carrying more than 400 enslaved people from Mozambique in December 1794.
